Claims.

Other important objects and advantages of my invention will be apparent from a reading of the following description and the drawings wherein a preferred embodiment of my invention is set forth for illustrative purposes.

In the drawings- Figure l is a side elevational view of the em-,

uodiment having a conventional enlarging camera associated therewith.

Figure 2 is a fragmentary transverse vertical sectional view taken through Figure 1.

Figure 3 is a horizontal sectional view taken through Figure 1 approximately on the line 3-2 and looking downwardly in the direction of the arrow.

Figure 4 is a fragmentary view similar to Figure 3 but showing the speciaicopying and projecting holder in place".

Figure 5 is a side or edge elevational view of the special copying and projecting holder slide.

Figure 6 is a top or bottom plan view of the holder of Figure 5.

Figure 'l is a top plan view of Figure 5.

Figure 8 is an end elevational view of Figure 5.

Figure 9 is a side elevational view showing the head reversed from the position shown in Figure 1 and having mounted thereon a printing head.

Figure 10 is a detail sectional view through a portion of thehousing and showing how a holder is held therein.

Referring in detail to the drawings, the nu-- meral 5 generally designates a suitable pedestal including the feet 6 and the tubular standard I rising therefrom and having vertically slidable thereon the open-work sleeve 8 to the upper part of which is attached a horizontally extending daddy-long-legs 8 terminating in a vertical bar It] whose upper end is swivelly connected at H to one side of the cylindrical housing 12. The bar 10 has a vertical slot l3 in its lower end for pivotal and sliding engagement with the pin ll on the lower end of the adjacent link of the extensible member 9. For printing operations the sleeve 8 may be reversed in position on the standard 1 as shown in Figure 9 wherein the cylindrical housing i2 is similarly reversed. A cable I! has one end connected at it to the member] and is trained over a pulley l1 supported on the upper end of the standard 1 through which the remaining end or the cable depends and is attached to a weight it which counterbalances the extensible member 9 and its burden. A fixed bracket I! on an intermediate part or the standard I has a crankhandle 20 mounted therein in operative relation to a screw 2| which is engaged to operate the slidable bracket 22 which supports the easel 23 at the required distance below the camera 49 or other instrumentality positioned above it.

The cylindrical housing H has mounted on its top the porcelainlzed dome 24, the connection 25 therebetween being annularly grooved as indicated at 22 to support the opal glass 21. The top of the dome terminates in an axial cupoia 28 through which supportably extends a conduit 28 for energizing and supporting a cluster 30 of suitable electric lights.

The interior of the cylinder I2 has a step-cut annulus 1i, acting as a plate or paper holder, removably resting on spaced lugs 32 positioned slightly below the upper end of the housing as shown in Figure 2.

The bottom of the housing I2 is open, the bottom edge thereof having abutted thereto the radial horizontal flange 22 on the annulus 34 which removably surrounds the lower end of the housing and is held in place by Studs 35 engaging bayonet slots 15'. The flange iii-acts as-a retainer tor the holder assembly which comprises the annular pan-shape 35 which has a square opening 31 termed through its center and coaxial with the cylindrical housing l2. The pan-shape 32 has four similar slots 38 distributed uniformly on four opposite sides thereof, through which the adjustable slides 28 extend to enable modifying the size of the opening 21. The slides have handles 40. On two opposite sides of the housing l2 motion picture iilm reels ll and 42- are mounted on the outside of the housing to feed motion picture through accommodating slots 43 formed in the sides of the housing-so that the film may extend across the opening 21, whereby downward projection of the film is provided for.

Electric lights 44 (for use only with the special holder to be described) are horizontally positioned as indicated in Figures 2, 3 and 4 circumferentially around the top of the pan-shape It, with suihble insulated conductors 45 leading thereto from outside of the housing i2.

The pan-shape It has depending from the bottom thereof two L-shaped enlarging camera slides l8 and 41 between the edges oi the openlog I! and the sides of the houlng It to receive the upper part 48 the enlarging camera 49 having the opening 49', as shown in Figures 1, 2 and 4.

The glass 58 rests in the special holder II thereby supporting the picture II on which rests the metal sheet 54. The special holder ll fits in the special slide 5!, the latter consisting oi a circular metal plate 51 having depending diametrically opposed laterally slotted lugs ll and U0 and diametrically disposed blocks '0 and II between them. Fixed on the top 01 the plate I! along the longitudinal edges oi the elongated opening 82 are the holder receiving brackets ll and N which are reiniorced by respective braces 88 and 86. The ends oi the opening 82 have angulated corners as indicated at .1. As shown in Figure 10, the holder 56 is mounted in the housing I! by a pair of diametrically opposed bolts provided on their radially inward ends with wing nuts H and II thereon to bear against the inner sides of the lugs 58 and 59, respectively, with the slots of these lugs engaging the shanks oi' the bolts.

In Figure 9 is shown an ordinary printing box arrangement 88 connected by means oi the camera connector slides 46 and 41 to the cylindrical housing I2 with the latter in an inverted position instead of its usual erect position.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not wish to limit the application or my invention thereto except as may be required by the scope of the subioined claims.
